To all whom it may concern..-

Be it known that I, JosEPH E. TYNAN, of Paterson, in the county ofPassaic and State of New Jersey, have invented an Improvement in SpindleSupporting and Driving Devices for Spinning-Machines, of which thefollowing is a specification.

This invention relates to the spindle-bolsters, bolster-sockets, andmeans for driving the spindles and supporting and lubricating the parts.

This improvement is especially adapted to doubling and twistingmachines; but it may be used in spinning-machines.

Figure 1 is an elevation of two of the spools and mechanism for drivingthe same in a silkdou'bling machine, a portion of the frame withthe'rails and belt-shifter in section, and adj acent'parts of themachine being also shown. Fig. 2 is a sectional plan at the linear a: ofFig. 1. Fig. 3 is a vertical section,in larger size,of ,the bolsters,bolster-sockets, driving-pulleys, and rail, the spindles and supportingrods being in elevation; and Fig. 4 is a sectional plan of part of therail and the bottom of the bolster-socket, the screws being inelevation.

Reference is hereby made to my application for patent No. 108,581, filedOctober 10, 1883, for a more full description of those parts that areonly briefly mentioned herein, the present application being a divisionof my said application No. 108,581.

The spools a and b, Fig. 2, contain the threads that are to be twistedand laid togather, and the spool or bobbin P receives the thread astwisted together and wound upon such spool. The spindles a b Q receivethe respective spools a b P. The spindles a b will usually be slightlytapering, so that the spools will be held thereon when pressed down toplace. The ring and traveler h and rail 0 are to be of any ordinarycharacter, and will be raised and lowered to lay the thread upon thespool P by the usual mechanism.

Upon the spindle Q there is a friction-disk, c, with a pulley, T, belowit, and U is a loose pulleyupon whichthe driving-belt wisshifted whenthe belt-shifter is moved to stop the spindle.

The spindles a b have upon them, respectively,the friction-disks a b,the edges of which are in contact with the edges of the disk 0 of thefast pulley T, and hence the spindles a 11 receive motion from thispulley T. The bolster-sockets form also oil-receptacles. Thebolster-sockets 13* for the spindles a b are made with flanges 44,resting upon thebolster-rail a, and said sockets B have screw-threads attheir lower ends for the clamping-nuts 45, below such rail a. The nuts45 are tightened after the sockets have been adjusted by the screws 46.

Thebolster-sock et R, where it passes through the bolster-rail a, ismade with an enlargement above-the rail to form the oil-cup r, and alsoto give a bearing upon the surface of the bolster-rail to retain thebolster-socket and spindle ina vertical position, and the hole throughthe rail is larger than'the bolster, so that the bolster-socket R andspindle Q may be drawn toward the spindles a N by the action of the beltw which passes around the fast pulley T, to insure the necessaryfriction between the disks a, b, and 0", but it is remarked that themeans for driving the spindles are not claimed herein, but are expresslyreserved forsaid application No 108,581.

'50 is a spring between the nut 51 on socket Rand the rail a to allowthe parts to yield s1ightly,but to maintain the bolster and spindle in avertical position, and 52 is a pin in the bolster-socket passing into aslot in therail a to prevent the bolster-socket revolving. tubularbolsters S are similarly made for all the spindles at 72 Q. They areadapted to receive the lower ends of the spindles, and each one has ahemispherical bearing,i ,around the central portion passing into asimilarly-shaped recess at the top of the bolster-socket, and there isto be a hole, 60, Fig. 3, through said bearing '5 for oil to flow down,and apin pass ing through the upper end of the bolstersocket into thebearing, as at 39, prevents the bolster revolving. By. this constructionthe bolster is hung by its hemispherical bearing, and this is in line,or nearly so, with the fast and its tubular bolster may vibrate above orbelow the bearing 73 without varying the action of the pulleys. Theedges of the friction-disks are preferably segments of globes The pulleyand the friction-disk,so that the spindle enters a hole in the lower endof the screwstep I). The screw-step slides freely down over the end ofthe spring, so that the weight of the parts is taken upon the bearing2". The springp tends to keep the bolster and spindle vertical; but ifthe bobbin is not true the spring yields and allows the bobbin andspindle to find their own axis of rotation. \Vhen the spring passes upthrough the bottom of the bolster, its upper end forms the step for thespindle,and by inalcingthe screw-thread upon the spring itself theaforesaid adjustment may be effected. In this latter case the springshould not pass through the lower end of the bolster-socket, because ithas to be inserted with the bolster from above, and cannot be driven intightly from below the bolster-socket; hence I bore the hole for thespring from the inside of the bolster-socket, but do not-bore it all theway through, as shown in connection with the bolster-socket B. If thelower end of the spring is squared and the hole in the bottom of thebolster-socket made of the same shape, the bolster and step will be heldso thatit willnot turn, and the pin 39 may be dispensed with. There areopenings (31 in the lower part of the bolster to allow the oil to passinto the spindle from the bolster-socket.

Around the spindle Q, below the fast pulley T, is the loose pulley U,that has a'hub that iits upon the outside of the bolster-socket R, andthis hub revolves in the oil box or cup 1', and there is a flange, 'r",at the lower end of this loose pulley U, to prevent the cord or belt wcoming into contact with the oil-cup r,aud the downward flange, r withinthe oil-cup, prevents oil being thrown out by centrifugal action,and theflange i- 'aids in excluding dust. There is a cylindrical dam, r withinthe oil cup, which prevents air-bubbles and froth that may form on thesurface of the oil at the loose pulley, causing the oil to be displacedfrom the oil-cup, because the air-bubbles, as they accumulate and passover the dam, are broken to a large extent by the upper edge of saiddam. The disk '0 upon the standard 12 for preventing either of thespindles being lifted when a spool is pulled off, is not claimed herein,as a device of this character is shown in my Patent No. 279,674,datedJune 19,1883. The drop-bar m, belt-shifter a, and frictionbrake a, andthe feed-roller, stop-motion, and other devices employed with spindles,bolsters, and driving mechanism are shown in my application No. 108,581,filed October 10, 1883, and do not form any part of this application.

I claim as my invention 1. The combination, with the spindle andbolstersocket provided with a hemispherical recess at its upper end, andhaving a closed lower end, of a bolster having a hemispherical bearingentering said recess and resting therein, and a step for the spindle,and a vertical rod forming a spring passing into the bolster-socket andbolster, respectively, to allow a limited rocking movement of thebolster upon the hemispherical bearing, and a fric' tion-disk around thespindle and in line with the center of the bearing, and a frictionaldriving-disk for the same, substantially as specilied.

2. The combination, with the spindle, of a b0lster,'a bolster-socket,forming also an oilcup, a screw-step, and a spring passing into thebottom of the bolster-socket and into an opening atthe bottom of thebolster, substantially as set forth.

3. The combination, with the spindle, of a bolster having ahemispherical bearing around it and provided with a screw-step, and abolster-socket having a hemispherical bearing, and a spring passing intothe lower end of the bolster-socket and into an opening at the lower endof the bolster,substantially as set forth.

4. The combination, with a spindle, of a bolster having a hemisphericalbearing, and a bolster-sockct having a hemispherical recess for saidbearing, a frictioirdisk in line with the center of said bearing, and adriving-pulley below the disk, and an adjacent spindle and driving-diskupon the same and in contact with the aforesaid friction-disk,substantially as set forth.

5. The combination, with a spindle, a bolster, and bolster-socket, of aloose pullcy,thc hub of which surrounds the bolster-socket, an oil-cup,and a cylindrical dam in said oil-cup, for the purposes andsubstantially as set forth.

6. The combination, with two spindles, of bolster-sockets havinghemispherical recesses, bolsters having bearings fitting such recesses,yielding supports at the lower end of the bolsters, means, substantiallyas specified, for preventing the bolsters rotating, a driving.- pulleysurrounding the bolster-socket and attached to one spindle, a diskconnected with the driving-pulley, and a disk upon the second spindle,with which the driving-disk comes into contact, such disks being inline, or near the centers of the hemispherical bearings, sub stantiallyas specified.
